摘要： A reverse flow air filter arrangement is provided. The arrangement includes a filter element having first and second end caps, the second end cap having a central drainage aperture. A funnel shape on an interior surface of second end cap is used to direct moisture flow to the drainage aperture. The arrangement includes a housing in which the filter element is positioned, operatively, during use. Certain features in the housing facilitate moisture withdrawal from the filter element while also inhibiting interference with sealing between the filter element and the housing.
